Microalgae play an important role in the chromium bioremediation. Biosorption is a method of bioremediation where sorption is taking place either by using dead or living biomass, and it has various significant advantages as follows:

1 (i) High efficiency in eliminating heavy metals even from very low concentrations

2 (ii) Cost effective

3 (iii) High metal adsorbing capacity

4 (iv) The ability of recovering the important metals adsorbed

Algal cells are considered as natural ion-exchange matter as they contain various anionic groups on their surface and this allows them to eliminate heavy metal ions efficiently [46, 47]. It has been observed that various strains of algae like blue-green algae, green algae, red algae, and diatoms are able to remove hexavalent chromium from soil and water.
